|Description||Trifluridine (NSC 529182, NSC 75520, Viroptic, Trifluorothymidine, TFT) is an anti-herpesvirus antiviral agent by interacting viral DNA replication, used primarily on the eye.|
Trifluridine inhibits proliferations of mouse bone marrow cells and human colorectal carcinoma cells implanted to nude mice dose-dependently. Trifluridine inhibits colony formation of bone marrow cells in a concentration-dependent manner.  Trifluridine (FTD) and 2'-deoxy-5-fluorouridine (FdUrd) are incorporated into DNA with different efficiencies due to differences in the substrate specificities of TK1 and DUT, causing abundant FTD incorporation into DNA. FTD-treated cells shows differing nuclear morphologies compared to FdUrd-treated cells.  Trifluridine inhibits proliferations of mouse bone marrow cells and human colorectal carcinoma cells implanted to nude mice dose-dependently. 
|In vivo||Trifluridine has significantly fewer swabs positive for HSV-1 than the untreated eyes in the infected rabbits.  Trifluridine has increased antitumor activity and is incorporated into DNA more effectively than continuously infused Trifluridine in mice. Trifluridine gradually accumulates in tumor cell DNA, in a TPI-independent manner, and significantly delays tumor growth and prolonged survival in mice, compared to treatment with 5-FU derivatives.  Trifluridine results in significantly lower viral titers, fewer HSV-1-positive eyes/total during the treatment period, lower keratitis scores, fewer eyes with keratitis/total, and a shorter time to resolution of keratitis in the New Zealand rabbit ocular model. |

1.Please make sure the liquid is clear before adding the next solvent.
2.Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (mg) = Concentration (mM) × Volume (mL) × Molecular Weight (g/mol)
*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and SDS / COA (available on product pages).
Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:
Concentration (start) x Volume (start) = Concentration (final) x Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )
* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and SDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
